mynewpool,
If you are losing .5 - 1" daily, I would suspect a leak regardless of heat/humidity.
Maybe not that much as I dont get out and actually measure it. I would say maybe 1 inch every 4-5 days or so.
Edit: It is also hard for me to tell as my dog when she is outside she loves to takes dips all the time. So splash out proably has something to do with it and her getting in and out a lot. I have done the overnight and lose nothing.
I also have a koi pond that is losing water as well and it is not exposed to sun at all, in complete shade and loses water.
